only two false molars on each side of the upper jaw. With this 

 exception the development of the whole of the teeth appears to be 

 complete. 



Tlie small size of the Er. Spafangus, its elongated form, the 

 regular disposition of its spines, the more rounded form of its ears, 

 and the comparative length of its hinder foot, distinguish it from 

 the other species exhibited, which Mr. Gray was disposed to consi- 

 der as the £r.co//«m figured in the 'Illustrations of Indian Zoology,' 

 but which Mr. Bennett rather regarded as a new species, it being 

 destitute of a white collar, and differing in other particulars from 

 the figure referred to. Mr. Bennett accordingly characterized it 

 as the 



Erinaceus Grayi. Er. auriculis long'is: spinis irregidariter in- 



tertextis, Jinvescenti apicnlatis nigrescentique annulatis ; capite

 The form of the body is broadly oval, approaching to globular. 

 The spines are yellowish-white for about five eighths of their length, 

 then ringed with blackish, and are terminated by a yellowish tip of 

 about one eighth of their length : hence results a general colour of 

 grizzled yellow and black. 



The head is brown above, with an intermixture of white hairs. 

 The ears are covered with short whitish hairs. The hairs of the 

 chin and lower jaw are also white, with the exception of a patch of 

 brown in the middle of the hinder part towards the throat. The 

 under surface is pale brown. 



The ears are less thickened towards the tip, and more acuminated 

 than in the preceding species. Hhe moustaches do not reach beyond 

 the tips of the ears. 



In the younger specimen the colour, both of the upper and under 

 surface, is much darker than in the adult. 



The exhibition was resumed of the new species of Shells collected 

 by Mr. Cuming on the western coast of South America and in the 

 islands of the South Pacific Ocean. Those exhibited on the pre- 

 sent occasion were accompanied by descriptions from the pen of 

 Mr. Broderip.
